固体发动机单项点火试验研究

Study of Single Ignition Test of Solid Rocket Motors

通过单项点火试验研究点火瞬态点火药量对点火装置点火延迟时间的影响以及不同点火药量、不同堵片打开压强下点火燃气在燃烧室流动过程,结果表明:点火装置延迟时间随着点火药量的增加而减少,发动机点火延迟时间、燃烧室内燃气填充时间、压强变化规律与点火药量和堵片打开压强有关。

By Single ignition tests to study the influence of mass of ignition powder on the ignition transient of the igniter and the flow of gas in different mass of ignition powder and the opening pressure of the nozzle closure.The results indicates that the ignition delay of the ignitor decrease with the increase of mass of ignition powder,the ignition delay of motor and the gas-filling time and the pressure in chamber is related with the mass of ignition powder and the opening pressure of the nozzle closure.
